- Remote attestation is initiated by Ignition but performed by the attester, isn't it?
- By "attestation token", you mean one à la https://github.com/confidential-containers/trustee/blob/main/attestation-service/docs/grpc-as.md#quick-start? Is it going to verify against Trustee (that should be in the diagram) or something else (what/how?)?
- Interaction between Ignition and Trustee attester for the disk key phase maybe?
- I know the diagram in the booting design document is mighty large as is, but I'm not sure I'd split it up this way where the reader must basically merge this diagram into a bigger slightly inaccurate diagram in their head to understand the flow. It would be easier if they could append two diagrams, e.g. if you split by phase? Then you could drop the registration service in the second phase.
